WARNING: This Maintenance Pack 1 (MP1)
fixes particular problems reported by Excelsior JET users and
discovered by Excelsior test engineers after version 3.15 release.
It has not been tested as thoroughly as the original 3.15 release,
so if you do not experience any severe problems,
such as compiler or application crash or incorrect application behavior,
and do not need to switch to the latest JRE (micro)version,
we recommend you to NOT install MP1 for use in a production environment.

Installation Instructions

The Excelsior JET 3.15 MP1 download contains the complete product.
Before installing MP1 on a system that already has the original version
installed you should either uninstall that original version or act as follows:

Let's assume that you have Excelsior JET 3.15 installed in C:\JET315.
Before installing MP1, rename that directory, say, to C:\JET315BACKUP.

During installation of MP1, specify C:\JET315 as the installation directory.

Now, should you need to switch back to the original 3.15, simply rename
the directories so that the version you currently need is in C:\JET315.
